Contactless Current Measurement Device with the Anisotropic Magnetoresistors

Original language description

A device for the contactless current measurement with Anisotropic Magnetoresistive sensors (AMR) has been developed. As the AMRs are much more sensitive than classically used Hall sensors, no magnetic concentrator is needed. The realized device reaches so far the linearity error of ą60 ppm in the current range of ą11 A for DC, i.e. the absolute resolution is ą1.3 mA. And the error due to non-concentric wire is less then ą0.6 %. The influence of the external current is reduced more then 45 dB.
